Intriguingly, HOXB9 and TGFβ2 expression was significantly upregulated in PCa cells carrying different combinations of CSC markers, compared with those in unsorted cells (ALDH+CD44+CXCR4+CD24+ > CD44+α2β1+ >CD44+ in terms of HOXB9 or TGFβ2 protein levels). This evidence concerns the gene LDHA and posterior cortical atrophy.
